2K FHD Smart Doorbell

The eufy Video Doorbell Camera C31 is a WiFi-connected smart doorbell designed for homeowners who want clear visitor identification without a subscription. It integrates with Amazon Alexa and Google Assistant for voice control and smart-home routines.

6500mAh Battery and Hardwire Power

A quick-release 6500mAh rechargeable battery enables wireless installation and mobility. When hardwired to existing doorbell wiring the unit supports continuous 24/7 recording; battery-only operation relies on motion-triggered capture and will require periodic recharging.

4:3 Aspect Ratio Field of View

The camera presents a 4:3 view that covers the full front-door area from head to package level. Buyers who need a wider horizontal panorama or a narrower vertical focus should note the fixed ratio cannot be changed.

Questions about this item

Will the C31 doorbell work with my existing mechanical chime when I hardwire it?

The C31 supports dual power; when hardwired to existing doorbell wiring the 6500mAh battery must remain inserted for proper function.

How do I verify the 2K FHD video and 4:3 view are working after installation?

Open the eufy app, start a live view and confirm the feed shows 2K resolution with a 4:3 aspect ratio covering the full front-door area.

What comes in the box and what must I purchase separately for 24/7 recording?

The package includes the doorbell and its 6500mAh battery; an SD card for local 24/7 recording is not included and must be bought separately.
